Paper Abstract

An integrated optimum athermalization design and analysis system will be developed in the study. The distance between the primary and secondary mirrors for a remote sensing instrument (RSI) will be taken as the objective function to improve the influence of the environment temperature variation on the optical images. Under a developing RSI model, the athermalization design to the secondary mirror based on the established system integrating a computer-aided design software, materials library construction, finite element analysis and optimization program will be executed. The design variables of the barrel, supporting structure and shims will be carried under low temperature change requirement. The displacements of the secondary mirror with respect to primary mirror with the optimum athermalization design can be reduced to almost zero from -95.6 μm for low temperature thermal boundary conditions.
